The 25-year-old stopped by the Playboy Mansion on Sunday to return the ring and Hefner's dog, Charlie, Hefner's rep confirms to Us Weekly. "It was the right thing to do," she told Radaronline.com of her attempt to return the jewelry.

While the 85-year-old mogul was thrilled to have his Cavalier King Charles spaniel back, he told Harris she could keep the engagement ring, along with the Bentley he'd given her, too, his rep confirms to Us.
